GENERAL DESGRIPTION As previously stated, this divisional application is.directedparticularly to therecord material,the mounting and controlthereon-and also the impression means and its control, adapted for usein a ,cash register or adding ,machine.

The record material, a ,fragmentary portion of which .is shown in Fig..5, is comparatively .wide, and is divided into nine vertical columns,the extreme lefthand column of which is considerably larger than .theother eight columns, and is used for the printing of the ledger numbersand all other identifying data, as well as amounts. "In addition, thelefthand column :is used :for the autographic entering of identifyingdata opposite the printed entries.

Likewise all totals and sub-totals are printed in'this wide lefthandcolumn and when the .ma-

chine is used as an adding machine, it is possible to print any amountdesired in this lefthand column.

When the machine is .used as a cash register,

cash and charge items cannot be printedin the amaze;

lefthand column, and therefore must be printed in one of the other eightcolumnar divisions located to the right thereof. Also, when the machineis used as a cash register, the received-onaccount and paid-out itemsmay be printed in the lefthand column, or in any other desired one ofthe eight columns of the record material. However, no-sale items areinvariably printed in the lefthand column.

The web of the record material is contained on a supply roll and isunwound therefrom and threaded around various guide rods, between theimpression mechanism and the printing mechanism, and thence onto areceiving roll. The entire record material mechanism, including thesupply roll, the receiving roll, guiding means therefor, and theimpression platen, is mounted in a framework which is rockable from anormal or reading position and return, to move the record material toand from printing position without the necessity of sliding the web ofrecord material over stationary guides and supports. When the recordmaterial is in reading position, the last few entries thereon arevisible through an opening in the closure of the cabinet, which closuregives access to the record material mechanism. Likewise, the autographicportion of the record material is accessible through said opening forthe autographic entry of descriptive data thereon.

The rockable framework which supports the record material is in turnsupported by a framework, which is removably mounted in the front of themachine and which is accessible through the closure above mentioned. Theclosure, which gives access to the record material mechanism, is notonly locked in closed position, but is automatically unlocked when atotal control slide (not shown in this divisional application) is movedto either Read total position or Add and Reset position. When theclosure is open the removable framework may be easily removed from themachine, and as this framework carries the rockable framework, theentire record material assembly, including the supply roll and thereceiving roll, may be quickly and conveniently removed from the machinefor the changing of record material, or for the making of adjustments tothe record material mechanism.

As the record material framework is rocked from reading position toprinting position, a portion of the guiding means for the web of therecord material is momentarily retracted, to release the tension on theweb of said record material, and while the tension is thus released theautomatic means for rotating the record material receiving rollfunctions to line-space the record material. A key located on thelefthand side of the keyboard is provided for actuating mechanism whichrotates the record material receiving roll for manually advancing orline-spacing said record material.

DETAILED DESCRIPTION Machine framework and operating mechanism Themechanism of the machine is supported by two main frames 60 and BI(Figs. 1 and 6) secured to a base which is not shown in this divisionalapplication. All of the mechanism of the machine is also enclosed in asuitable cabinet 69, a portion of which is shown in Fig. 1.

A conventional type of electric motor (not shown herein) drives a mainshaft E30 (Fig. 3) one clockwise revolution for each operation of themachine.

PRINTER Type wheels Type wheels 3H! for the four lower order amountbanks are supported in a shiftable framework which is positioned underthe influence of column selecting keys to select the different columnsof the record material (Fig. 5) for the entering of various items.

There is only one type wheel 1H9 shown in this divisional application.The mechanism for differentially positioning the type wheels 3I9 and theshiftable framework for shifting the type Wheels is not shown in thisdivisional application, but is fully illustrated in the parentapplication, Serial Number 430,214.

Record material mechanism The supply and receiving rolls for the recordmaterial, shown in Fig. 5, are supported in a framework which isremovably supported between the main frames of the machine, and which islocated at the front of the machine where it is accessible through aclosure in the cabinet portion of the machine. The closure giving accessto the record material is locked in closed position when the totalcontrol slide (shown and described in the parent application, SerialNumber 430,214) .is moved to either the Read total position or the Addand Reset position. Therefore, the record material is accessible only tothose having keys to a lock in the total control 1 slide, which look isused for locking the slide in either Register position or Lock-registerposif 315 tion.

, said opening being covered with a transparent The last few itemsentered on the record mate- 3 rial are visible through an opening in thetop part of the closure giving access to the record material,

material such as glass or pyralin. The extreme lefthand portion of therecord material is reserved for the autographic entering of variousdata, and an opening in said transparent material gives access to thisportion of said record material for this purpose.

Referring now particularly to Figs. 1, 2, 3, 6,

and 9, the removable framework for supporting the record material supplyand receiving rolls comprises a right plate 126 and a left plate 121connected in fixed relationship to each other by a rod 128. Trunnionsformed by opposite ends of the rod 128 engage curved slots 129 in eachof two similar plates 130 and '13! secured, respectively, to the rightside frame BI and to the left side frame 60. Similar extending legs ofthe plates 12B and 12'! have identical inverted V- shaped notches I32and 133 adapted to engage, respectively, the circumference of similarhubs secured in axial alinement with each other in the frames 69 and GI,said hubs providing bearing supports for a shaft 134. The rod 128, in

cooperation with the curved slots 129, forms a I35 (Figs. 1 and 6)pivoted on studs 136 in plates 126 and 121, are urged clockwise bySprings 131 into engagement with stationary studs 138 in the frames 60and 6|, to latch the record material framework in operating position, ashere shown. 4

To remove the record material framework from the machine or to swingsaid framework to a more accessible position for the removal of theprinted portion of the record material wound on the receiving roll,bent-over finger-pieces 139 on the two latches 135 are grasped, and saidlatches are rocked counterclockwise, as viewed in Fig. 1, against theaction of the springs 131, out of en'- gagement with their respectivestuds 138, after which the entire record material framework may berocked outwardly or counterclockwise, the rod 128 andthe slots 129forming a pivot for said framework until similar projections 14! ondownward extensions of the plates 125 and 121 come into contact with thestuds 138 to terminate rocking movement of said framework and to holdsaid framework in an accessible position. If it is desired to remove theframework from the machine, the rod 128 may be lifted out of the openupward ends of the slots 12-9.

A supply roll 142 (Figs. 2, 3, 6, and 8) is rotatably supported by aframework comprising end plates 143 and 144 maintained in spacedrelationship to each other by a rod 145 and a shaft 146, both freelyengaged by said plates. The framework ror supporting the supply roll 142is rotatably mounted between the plates 126 and 121 by means of twoaxially alined trunnion studs 141 in each of the plates 143 and 144 incooperation with hubs 148 in said plates 126 and 121. The web of thesupply r'oll 142 is wound around a metal tube or core 149 (Figs. 6 and8), the inside circumference of one end of said core 149 fitting over atenon of an axle 1'59 journaled in a bushing in the plate 144, and theinside circumference of the other end of said core 149 fitting over asimilar tenon on a spring-pushed plunger rotatably mounted in a bushingin the plate 143, said plunger 15! being in axial alinement with saidaxle 150.

To mount the supply roll 142 in the framework 143 and 144, the righthandend of the core 149, as viewed-in Fig. 6, is slipped over the tenon ofthe spring-pushed plunger 15!, and said plunger is pushed to therighta'gainst the action of its spring until the lefthand end of thecore may be slipped over the tenon on the axle 150. Each of the plates125 and 121 (Figs. '1, 2, 6 and 9) has an identical cam'ming slot 152,which slots are engaged by similar rollers 153 on two similar levers154, rotatably supported on opposite ends of the rod 145. 'Rearwardlyextending arms of the levers 154 support a rod 155, said rod in turnbeing pivotally connected by two similar links 158 (see also Fig. 8) toreceiving roll support arms 151 and 158 secured in fixed relationship toeach other on the shaft 146.

By referring to Figs. 6 and 8 it will be seen that the web of the recordmaterial is unwound from the supply roll142 and threaded around the rods145 and 155 and a rod 159 supported by the arms 1'51 and 158, thenceonto a core 18!! for a record material receiving roll 18!. The core 168'i's-sim'ila-r'in every respect to'the core 149 for the supply roll, andis rotatably supported between the arms 151 and 158. r

The righthand end of the r'eceivingroll core 160 has therein twodiametrically opposed clutch cuts adapted to engage two diametricallyopposed tenons'on'a clutch 162 (Fig. 10) secured on the end of aplunger-like axle 153, rotatably supported in a bushing 184, secured inthe arm 151. Also secured to the axle 183 is a knurled finger wheel 1 55-'having thereina slot which engages an angular tongue 1B6 ona disk 161secured to amend f'a hub'168 rotatably'mounted on the axle 16 3. The hub168 has-secured-on the'otherend-thereof ating connection between thesetwo parts.

a disk 189 and a receiving roll feed ratchet 118. A feed pawl 11! (Figs.6, 10 and 11) pivoted on a stud 112 carried by a paper feed disk 113,free on the axle 183, is urged into engagement with the teeth of theratchet by a spring 114. Likewise a ratchet retaining pawl 115, free ona stud 118 in the arm 151, is urged clockwise (Fig. 11) into engagementwith the ratchet by a torsion spring 111. The disk 113 carries a studpivotally supporting the lower end of a link 18! (Fig. 8), the upper endof which has a slot 182, which embraces the tenon of a stud 183 in alever 184, free on the rod 145. The lever 184 has therein a hole whichfreely engages a tenon of a stud 185 secured in the lever 154 (Fig. 2.).

Inasmuch as the record material feeding means is operated in conjunctionwith the impression means, the manner in which the lever 154 operatesthe record material feeding mechanism, described above, will "beexplained presently in connection with the description of saidimpression means.

The leithand end of the core 160 for the receiving roll 15! (Figs. 6, '7and 8) is supported by a pilot washer 188 which engages the insidecircumference of said core, said washer 186 being riveted to'the face ofa spring-pushed plung er 181 having two diametrically opposed tenonsadapted to engage two diametrically opposed clutch cuts in the lefthandend of the core 188. The tenons on the plunger 181 engage correspondingnotches in the large diameter of a counterboring in a ratchet 189 toform an oper- The small diameter of the counterboring in the ratchet 189rotatably mounts said ratchet on a fixed stud in the arm 158. A hubportion of the ratchet 189 has therein an annular groove which isengaged by "a retaining clip 198 (Fig. 7) secured to the arm 158 to holdthe ratchet and connected parts against lateral displacement.

A ratchet operating pawl 19! (Fig. 9) has a slot 192 which fits looselyover the rod 159, and a torsion spring 193 urges said pawl 19% clockwiseand rearw'ardly to normally maintain a tooth on the forward end thereofin contact with the teeth of the ratchet 189.

A disk 188, secured to the face of the ratchet 189, and the face of thefinger wheel 155 (Figs.

7 and 10') form flanges for guiding the web of the record materialaround the core 199. Said disk 188 also serves to maintain the tooth ofthe pawl 19! in lateral alinement with said ratchet 189.

When the record material framework is in normal or reading position, asshown in Fig. 9, a rounded surface '194 on the pawl 19! is in operatingrelationship with a stud 195 in a lever 195 pivoted on the shaft 134. Aboring in the lever 196 is freely engaged by a tenon of a stud 191 inthe lower end of a link 198, the upper end of which link is pivotallyconnected to one arm of a lever 199, free on the shaft 2!2. A stud 898in another arm of the lever 1'99 engages a slot in the stem of therecord material space key !95, said key havin parallel slots thereinwhich engage studs 88! and 892, secured to the left frame 80. A spring803 urges the key !95 upwardly to normally maintain said key andconnected parts in normal position, as shown in Fig. 9.

Depression of the key 95, when the record material framework is innormal position, as shown in Fig. 9, rocks the lever 199 clockwise,which through the link 198 rocks the lever 196 counterclockwise, causing'the'stu d --H-l5 in -co- 7 operation with the surface 194 to shift thepawl 19! forwardly against the action of the spring 193 to rotate theratchet 189 and the core 160 one tooth-space to line-space the record material. A retaining pawl 804 free on a stud in the arm 158 is urgedcounter-clockwise by a torsion spring H9 to normally maintain the toothof said pawl in engagement with the teeth of the ratchet 189 to preventretrograde movement of the ratchet and the record material receivingroll 16! In applying the receiving roll core 160 the righthand endthereof, as viewed in Fig. 6, is slipped over a pilot washer 118 (Fig.secured to the face of the clutch 162, after which said clutch, thewheel 165 and the axle 763 are depressed against the action of theirspring until the lefthand of the core 160 may be slipped over the'pilotwasher 788 (Fig. '7). The washer 186, together with its plunger 181, isforced inwardly into engagement with the core I80 by a compressiblespring in the counterboring in the ratchet 189. After the core 160 hasthus been mounted in the printer framework, the knurled finger wheel 165(Fig. 10) is rotated manually until the tenons of the clutch 162 and theplunger I81 drop into their corresponding clutch cuts in opposite endsof the core 160 to operatively connect said core to the automaticline-spacing mechanism and to the hand line-spacing mechanism.

- After the core 160 is thus mounted in the record material frameworkthe web of the record material is unwound from the suppl roll [42 (Figs.8 and 9) and threaded around the rods 145, 155 and 159, after which theend of the web is inserted in a slot in the core 180 and said core isrevolved manually by the finger wheel 165 to start the record materialwinding around said core 160.

Impression mechanism The impression mechanism for printing in any of thecolumns of the multi-column record material shown in Fig. 5, comprises aplaten which extends across the width of all printing columns of therecord material, said platen being operated by a toggle arrangementwhich causes a squeeze type of impression to be effected rather than theconventional hammer--blow type of impression. The impression mechanismis supported by the framework 183 and 144 which moves the recordmaterial from reading position to printing position and return, andobviously said printing impression mechanism moves in unison with saidframework. Therefore, when the machine is at rest, the impression platenis in a non-printing or substantially vertical position, as shown inFig. 2, and during the machine operation said platen is moved fromnon-printing position to a printing position, as shown in Fig. 3, andthe impression mechanism is simul-- taneously engaged with its operatingmechanism, which upon oiperation causes the platen to squeeze the recordmaterial and the inking ribbon into contact with the type wheels 3E9 torecord the data relating to the machine operation being performed.

The impression mechanism comprises righthand and lefthand arms 805 and806 (Figs. 2, 3 and 6) similar in outline and each having similar slots88? which engage the trunnions 14'! carried by each of the plates 143and 144. Similar slots 808 in the lower ends of each of the arms 805 and806 and parallel to the slots 801, engage studs 8 809 carried by theplates 14'3'and 144, to slidably mount said arms 805 and 806 in therecord material framework. Each of the arms 805 and 806 has on the upperend thereof inturned ears, which straddle similar ears on a U-shapedplaten support bar 8| I, each set of ears being pivotally connected toeach other by means of pins Bill which pass through borings therein. Thechannel formed in the U-shaped bar 8 (Figs. 2 and 6) supports a longresilient impression block 812, which is secured against displacement bythree v screws threaded into the side of the channel bar,

said screws having pointed ends which penetrate the resilient platenblock M2. The bottom of the platen block an rests on a long adjustingplate (not shown) supported in the channel of the bar 8| I, said platebeing adjustable by means of screws threaded into the bottom of theframe, to in turn adjust the face of the platen block M2 in relation tothe type wheels 3l9.

When the framework which supports the record material is rocked fromreading position, as shown in Fig. 2, to printing position as shown inFig. 3, the platen block 812 and its supporting framework also move inunison therewith and the line-spacing mechanism functions in a manner tobe presently described to cause the record material to be automaticallyline-spaced prior to operation of the-impression mechanism.

Mechanism for rocking the rocking material framework from non-printingposition to printing position and vice versa, comprises two identicalstuds 813 (Figs. 3 and 6) carried by the plates I43 and M4, said studsadapted to be engaged with notches in the upper ends of similar arms 8H3when the printer framework 126 and 127 is properly mounted in themachine, as shown in Fig. 2. The lower ends of the arms 8 M are slottedto embrace a shaft 488 journaled in the frames 60 and ti, and each ofsaid arms carries a stud 815, which extends through corresponding slotsin each of two arms 818 secured to the shaft 488. A compressible spring8H forms a resilient connection between the pair of arms 8M and MS andconstantly urges said arms 814 upwardly to maintain the notches thereinin engagement with the studs 813 (Figs. 2 and 3) regardless of theangular relationship of said studs to the shaft 488.

Secured to the shaft 488 (Fig. 3) is a crank 489 having pivoted theretoa pitman 490 carrying a roller 49! (Fig. 4) cooperating with a camgroove 492 in a cam 493, which is secured to the main drive shaft I30.This cam groove 492, through the pitman and crank, rocks the shaft 488first counterclockwise and return.

Initial movement counterclockwise of the shaft 488 (Figs. Z'and 3) rocksthe record material framework 743 and M4 from the position shown in Fig.2 to the position shown in Fig. 3, to bodily move the record materialsupply roll M2, the receiving roll and the impression platen 8l2 fromreading position to printing position. As the impression platen BIZ andits assembly move to printing position, the cam slots 152 (Figs. 2 and3), in cooperation with the rollers 153, rock the levers Z54 clockwisein relation to the record material framework, which is also moving in aclockwise direction at this time. Clockwise movement of the levers 154through the stud carried by the righthand lever 154 (Fig. 6) imparts asimilar movement to the lever 184 (Fig. 8) which by means of the stud183, in cooperation with the slot 182 shifts the link 'l8l forwardly torock the disk 113 (see also Fig. 11) also in a clock-, wise direction.Clockwise movement of the disk (Figs.

9 [13 (Figs. 3 and 11) causes thefeed pawl I'll carried thereby, incooperation with the teeth of the ratchet H0, torotate the core 160(Fig. 10) and the record material receiving roll lfil the equivalent ofone tooth space to line-space the record material prior to operation ofthe impression mechanism.

Clockwise movement of the levers I54 (Figs. 2 and 6) through theconnections comprising the rod 155, the links 158, the arms 157 and 158,and the guide rod 159 slightly and momentarily collapses a portion ofthe record material guiding means to relieve the tension on the web ofthe record material while it is being line-spaced, to overcome thedanger of tearing said web and to prevent unnecessary strain on theline-spacin mechanism. I

Clockwise movement of the record material framework M3 and 144 fromreading position to printing position (Figs. 2, 3 and 6) engages twoaxia ly alined studs 8l8, carried by each of the impression arms 805 and885, with notches in the upper ends of operating arms 828 and 82lsecured to the shaft 134. An extension of the arm 820 has pivotallyconnected thereto the lower end of a toggle link 8 22, the upper end ofwhich is pivotally connected by a stud 823- to a companion toggle link824 pivotally mounted on a stationary stud 825 in the right side frame8!. The stud 828 also pivotally supports the forward end of an operatinpitman 826, the rear end of which is bifurcated to straddle the shaftI38, said pitman carrying a roller 82'! which cooperates with a camminggroove 828 in the righthand face of the cam em. with the roller 821,shifts the pitman 828 first forwardly (to the left as viewed in Fig. 3)and then back to normal position, after the type wheels 3|9 have beenset by the differential mechanisms shown and described in. the parentapplication. Forward movement of the pitman 826, which occurs after therecord material framework has been rocked to printing position, as shownin Fig. 3, expands or lengthens the toggle links 822 and 824 to rock thearm 820, the shaft 134, and the arm 82! clockwise. Clockwise movement ofthe arms 82!] and MI shifts the impression arms 885- and 886 rearwardly(to the rigl'i as viewed in Fig. 3) on their supporting studs i8! and889 to cause the impression platen 852 to press the web of recordmaterial and an inkin ribbon 829 into contact with all of the typewheels to record the transaction on the web of record material as shownin Fig. 5.

After the impression has been made the pitman 825 is returned rearwardly(to the right as viewed in F g. 3) to shift the impression assembly tonormal position, after which the shaft 488 is returned clockwise by thecam groove 492 (Fig. 4) to restore the record material framework 143 andM4 to reading position. When the framework is in reading position, theposition of the record material carrying the recordings of the lasttransaction and several previous transactions is visible through anopening 830 (Fig. l) in a closure 83! hinged to the cabinet 69. Theclosure 831 encloses the. record material framework I26 and i2! and theopening 83f] is preferably covered with a transparent plastic material832. An opening 833 (Fig. l) in the transparent material 832 exposes thelefthand edge of the record material so that various data may beautographed thereon opposite theprinted records of the transactions, ifdesired. A table. 834

The cam groove 828, in cooperation and, 8) supported by the rods 7,45"and atom-e4 1.55 of the record material framework, is located directlybeneath the autographic opening 833 and provides a backing for the webof therecord material for the autographic entering of items thereon.

When the printer framework 126 and I21 is removed from the machine it isnecessary to latch the record material framework M3 and 144 in readingposition, as shown in- Figs. 1 and 6, so that the studs 8l3 will remainin alinement with the notches in. the upper ends of the arms 8M so thatsaid. studs. will, reengage said notches when the record. materialframework is again placed in the machine.v

This retaining of the rockable portion of the record material frameworkin reading position, as shown in Fig. 2,, is. effected by two identicallatches 835 (Figs. 1 and 6). pivoted on studs 836 carried by the platesv12% and 121. The latches 835 are urged clockwise by the springs 13!which are tensioned between. said latches. 835 and the latches 13.5,.which. latter latches secure the printer framework in operating,position, as previously explained. Each of the latches 835 has a stud831, which studs extend, through corresponding clearance openings in theplates 126 and 12'! and cooperate with corresponding camming surfaces838 on each of the plates 130 and HI to retain the hook-shaped upperends of said latches 835 disenga ed from the rollers 158, which it willbe remembered are carried by the levers 154, so that the record materialframework 143 and 144 may be rocked to and from printing position duringthe machine operation.

When the printer framework, including the plates [26 and 121, and allthe parts assembled therebetween, is. removed from the machine by manualrelease of the latches 135, in the manner previously explained,withdrawal of the studs 83'! from the surfaces 838 permits the springs73! to rock the latches 835. clockwise, as viewed in Fig. 1, intoengagement with the rollers 153 to secure the levers 154 and therockable record material framework in reading position, as shown in Fig.2 so that the studs 8| 3 will reengage the notches in the upper ends ofthe arms 814 when the printer framework is again placed in the machine.

As brought out in the general description of the impression mechanism,the printer framework is accessible through the closure 83I, which ishinged to the cabinet 69, and said closure is locked in closed positionwhen the machine is being used as a cash register or when the machine iscompletely locked against operation,

and is unlocked when the machine is set for either read, reset or addoperation, as has been fully explained in the parent application.

The closure 83l has two downward extensions 8 (one of which is shown inFig. 1) each carrying a stud 842 adapted to be engaged by thehook-shaped endsof two identical latches 843 pivoted on studs 844carried, respectively, by the frames 6! and 60, to normally look saidclosure 831 closed. Springs 845, tensioned between studs 845 in thelatches 843, and stationary studs 84! in each of the frames 60 and BI,urge said latches 843 clockwise into engagement with the studs 842. Anextending tip on each of the latches 843 cooperatesv with the studs 841to limit the clockwise movement of the latches 843, under the influenceof the springs 845, in relation to the studs 842, so that said studs mayproperly lay-pass the rounded noses of the. latches 843 when the closure83.1 is being closed.

The studs 84B cooperate with upwardly extending fingers of two latchoperating levers 848 pivoted on studs 849 in the frames BI and 68. Eachof the downward extensions of the levers 848 has an arcuate surface 85!!adapted to cooperate with camming nodes 85! on two identical cams 852secured on the shaft 459. When the machine is in the locked position sothat it cannot be operated, and also when it is in the position to beoperated as a cash register the cam 852 is inthe position shown inFig. 1. However, when the machine is in a position to take a readingoperation, a reset operation, or in a position to be operated as anadding machine, the shaft 459 is turned and the same nodes 85!, by theircooperation with the cam surfaces 858, rock the levers 848 clockwise,whereupon the latches 843 are rocked counter-clockwise and disengagedfrom the studs 842 to release the closure 83! so that it may be openedby the operator to gain access to the printin mechanism.

A tension device is provided for applying frictional drag to the recordmaterial supply roll T42 (Figs. 6 and 8), to insure that the web of therecord material is held taut when the record material framework 143 and144 is in either reading position or printing position, as shown,respectively, in Figs. 2 and 3.

The tension device includes a friction plate 853 (Figs. 6 and 8), havingbent-over ears which freely engage the shaft 146, this plate having aslot 854 through which extends a pin 855, free in a hole in said shaft[46. A torsion spring 856 loosely coiled around the shaft 148 has oneend thereof looped around an annular groove in one end of the pin 855 toretain said pin in place and the other end of said spring is loopedaround the downward edge of the plate.853. The spring 856 is tensionedto urge the plate 853 counter-clockwise, as viewed in Fig. 8, intofrictional engagement with the circumference of the supply roll 142 toimpart a braking effect to said supply roll to insure that the web ofthe record material is retained taut when the record material frameworkis in reading position or printing position.

The pin 855, in cooperation with the slot 854, prevents lateraldisplacement of the friction plate 853 on the shaft 146 and determinesthe extent of rotary movement of said plate under the influence of thespring 856.
